Storage devices: Storage devices are typically mounted in the system unit. Those involving removable media such as the floppy disk drive, the CD-ROM drive, and the ZIP drive are mounted on the front side of the system unit, and the hard disk drives are typically mounted inside the system unit. Commonly used storage devices are floppy disk drives, hard disk drives, CD-ROM drives, and ZIP drives: A floppy disk drive is a device that reads and writes data on floppy disks. A typical floppy disk drive uses 3 1/2-inch floppy disks, each of which can store up to 1.44 MB.A hard disk drive can store billions of bytes on a nonremovable disk platter.A CD-ROM drive is a storage device that uses laser technology to read data from a CD-ROM.

Personal computers also use floppy discs and CD ROM drives to store data. A 3.5 inch floppy disc has a capacity of 1.4 Mb. CD ROM drives have a capacity of 650 Mb and modern drives permit both reading and writing facilities.
Technological advancements and innovations are often detrimental for concerned technology companies
Published in International Journal of Computers and Applications, 2018
The technological landscape often changes very rapidly. Many technologies that were considered the most popular among people few years back might be facing extinction today. This does not happen due to natural or human influenced disasters but rather because of the advancements and innovations of the cutting-edge parallel and alternative technologies. In some sense, one technology kills another. Gone are the days of floppy disk which is already replaced by USB flash stick. Likewise, we once saw the boom of photographic film which is now obsolete in the age of digital camera. In fact, Kodak like companies producing photographic films faced huge revenue loss with the advent of digital camera [1]. Fax machines are being replaced by MFPs (Multifunction printers). The future is unpredictable but in many cases, it is more or less understood that with the advancement of technologies, some other parallel technologies suffer the most. Eventually, the concerned technology companies pay the price. This is even more practical especially in the field of Information and Communication Technology (ICT) and overall Computer Science and Engineering-related fields. Within quick time, even within a period of five years, we could see changes that were not imagined before. We have various indicators, some we know and some we guess but when the right parameters join together, the change occurs pretty fast. While there are often practical latest products emanating from real products existing at the current time, in the research arena, we are free to think (with some rationale) about almost anything, whether in future that becomes a reality or not.
